IMPROVEMENTV IN GAS-STOVES.

Specification forming part of Letters Patent No 163,344, dated May 18,1875; application filed March 5, 1875.

To all whom it may concern:

Be it known that I. JOHN J. WEST, of Ghicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inGas-Stoves, of which improvements the following is a full, clear, andexact description, which will enable others skilled in the art to whichmy invention appertains to make and use the said improvements, referencebeing had to the accompanying drawing forming a part hereof, and inWhichi.

Figure I is a side elevation of my improved stove 5 and Fig 2, avertical central section thereof.

Like letters of reference indicate like parts.

In the drawing, A represents the outer wall or case of the stove. Thispart of the stove may either be open at the bottom, and supported in anysuitable manner, or it may be perforated, as shown at e c, to admit theair, or these perforations may be employed in connection with an openbottom, for the same purpose. B is a gas-pipe terminating in thevertical slender pipe or tube B', arranged in the central part ofthestove. C is a partition or diaphragm arranged across the upper part ofthe stove, as shown; and D D are vertical flues passing entirely throughthe said partition. The pipe B' also passes through this partition, andterminates just above it. F is a diaphragm of wire-cloth arranged alittle Way above the flues D D, and pipe B'. G is a diffuser arrangeddirectly over the pipe B'. H is an annular arched ange projecting fromthe wall A inwardly, and arranged above the diaphragm F. e' c' areopenings in the wall A, and above the liange H; a continuous opening,however, may be employed instead of these perforations. I is a removablepiece or cap resting on the upper edge of the wall A. J is a flangeprojecting outwardly from the wall A, and arranged just below theopenings e' e'. The upper face of this flan ge is preferably concave, asshown. K represents the article to be heated. The Wall of the stoveextends sufficiently above the openings c e', to form a considerablechamber below the part I, as shown at I', and a considerable spacebetween the parts J and K.

In order to use my stove, the part I is arranged as shown, and the pipeB is connected to a gas-tip by means of a flexible tube. When the gas isturned on, it passes out at the end of the tube B', is spread in alldirections by the diffuser G, passes through the diaphragm F, strikesthe flange H, and is deflected by it, enters the chamber I', is againdeected by the part I, and passes out through the openings c' e',whereit may be ignited. The ame, owing to the pressure of gas and air,and to the form and arrangement of the iange J, which protects it atthis point from the influence of upward currents, will be` carried tothe edge of Jthe said ange, where it forms a continuous sheet, and thenextends upward, as represented in Fig. 2, thus making a very large flamein proportion to the size of the pipe B' By this means the air withinthe stove is thoroughly mixed with the gas, and when the stove isthoroughly heated a current of air will enter the bottom of the stove,or the holes c c, pass upward through the iiues D D, become highlyheated and mixed with the gas, and pass out with it, thus causing theflame to be impinged with greater force upon the flange J than resultsfrom the merc pressure of gas, 'and producing, to a considerable degree,the effect of ablow-pipe, besides further reducing the volume of gasrequired to produce a given degree of heat. The radiating surface, asWill be perceived, is large in proportion to the size of the stove,which will be found to be exceedingly useful, for many purposes, as aheater merely. In order to cook by means of this stove, the article tobe cooked or heated is placed across the top ofthe stove. The gas willbe mixed with the air and pressed out by the latter, even if thediffuser G, diaphragm F, and ange H tare not employed; but I deem itpreferable to employ the parts in the manner described, for the purposeof producing animproved result.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The chamber I', inclosed by the outer walls of the stove, and havingtherein the ports or openings c' c', in combination with the shield orflange J projecting from the out- 3.
